The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Highland, California (ZIP 92346), overall, ranks in the top 50% healthiest ZIPs nationally (16,029th) and the bottom 38% of California (1,063rd).
This area's measures are easy to read as a mixed set: PFOA in drinking water lies at the national maximum. Set against that, modeled expected annual loss stands in the top 2.0% nationally, PFOS in drinking water rests at the national maximum, and outer-floodplain exposure registers in the top 2.4% nationally. Modeled disaster risk resides in the top 2.7% nationally, and PFAS in drinking water settles at the national maximum. Distance to a Superfund site is in the bottom 5.9% nationally, and modeled colon screening sits in the bottom 6.9% nationally. Crowded housing lands in the top 7.9% nationally, and modeled air-toxics cancer risk lies in the top 8.3% nationally.
Measured against the nearby ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 92359, just across the boundary, comes out healthier overall.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 0.57 years of 77.7, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match. How distance is measured
